About AJ Ronan, DO

Twenty years ago, I went into primary care to help people of all ages improve their health. While it is always the goal to know your patients well and to understand all the things happening in their life that could be affecting their health, it can be challenging to accomplish in a traditional family medicine practice.  

MDVIP understands that what people need is more time with their primary care physician to discuss important health issues and to delve into the day-to-day challenges of trying to live a healthier life. In my MDVIP-affiliated practice, my focus is getting to know my patients better and developing more personalized healthcare plans to help meet their specific needs. My mission is to help patients achieve their health goals while living active and fulfilling lives – and to do that along with them by “walking the talk.” 

As one of the few family medicine doctors in the greater Lansing area offering this personalized healthcare approach, I have the ability to dedicate ample time to prevention and wellness. Similar to concierge medicine practices, I also offer conveniences like same- or next-day appointments that start on time. Education on these and other topics is one of my passions, and I have been on the teaching faculty at Michigan State University for over 15 years. In addition, I have a longtime interest in cardiometabolic disorders like high cholesterol, hypertension and diabetes, which are so prevalent in the United States and other developed countries of the world. I am excited to be able to offer more advanced cardiovascular screenings among other testing through the MDVIP Wellness Program and to delve more deeply into patients’ risk factors to help them stay ahead of their health.

What our members are saying

I have had discomfort in abdomen for a little over 12 years. I have been put on 5 different antacids. Each time I am prescribe a new one, the symptoms subside, but comes back. A Dr. changes to a new script, and the cycle continues. No Dr. ever really seemed to listen to what I tell them. They would nod, yes, I understand, that's why we are going to switch to this medicine. And the cycle…

I have been a patient for 20 years with dr Ronan. There have been so many moments that have been life changing for me because Dr Ronan really listens and takes time to address each concern I have always had. The first time seeing him I was suffering wide spread pain and depression drs before seeing him said it’s in your head the widespread pain is not real. I heard this multiple times and I was…

My early physical was scheduled right after my father's passing in February 2022. Dr. Ronan and I had a special bond where we would exchange stories about our parents, especially our dads. During my visits, Dr. Ronan would offer helpful tips and suggestions for my 81-year-old father, who had always been relatively healthy for his age. However, on this particular visit, I couldn't hold…

Dr.AJ Ronan has been my primary care doctor for many years. He has always been very caring about my health and is proactive about helping me solve a health issue. He spends more time with me in an office call as any other doctor ever has. He goes in depth to explain why, and what my medication’s will do, and how my medical issues can be dealt with such as ordering different tests and referring me to specialist. He is the best doctor I have ever had and I’m in my 70s. His medical staff is amazing.
I highly recommend Dr Ronan to anyone Who is looking for an amazing primary care doctor.
And 5 stars for Becky, who I talk to when I call And I’m sure she does a lot more in that office than anybody can imagine. She will give a follow up call to me. just to see if I’m doing OK!

My doctor Dr A J Ronan is the best doctor ever. Due to Eye Surgery I have not been able to drive myself to appointments etc. and my doctor and his PA Tom made a house call to see me and even offered to bring me food. I've never had that kind of attention with any doctor before. His Office Administrator, Becky also took time to drive to my house and bring me my medications on one occasion.

I never have to wait to be seen and I always feel heard. I have had my PCP for over 25 years so I have a great relationship with him and the staff and I love them. My doctor even told me that he loves me! Dr Ronan takes time and care with all of his patients. I don't want to ever have to get another PCP cause Dr Ronan and Staff are the best!

Positive experiences. Top notch staff. Very attentive, accommodating. Always able to get an appointment when I need one. Dr. Ronan called me the day I signed up for his practice, asked if there was anything I needed. This is before I ever had an appointment. Very pleased.

Hi Dr. Ronan, today I'm doing fine, I move around quite a bit, I have no trouble getting out of bed, or my car, or my couch, I don't sit around too much because I always have things to do and that keeps me moving. My problem is my A1C, otherwise I, doing fine.. If you need me to come in for a check up I can do that, just to see all of you. Have a great day. Gloria Sutton

I love it. I was just doing a home visit this morning and mobility came up. The couple I was seeing have concerns about travel overseas and limited mobility. We have made arrangements for physical therapy but I always tell my patients they have to keep moving to stay mobile. Timely subject matter.

I have been with Doctor A.J. Ronan since a severe neck injury in 1999 which he saved me from surgery via OMT. A great doctor and the most genuine person as well, excellent staffing, follow up. Now with MDVIP much more accessible as well, comprehensive and meaningful referrals for surgical or other procedures as needed with a realm of his contemporary local experts. So thankful for his help with all my health needs. He is the best in my opinion.

If you are looking for a doctor that takes the time to listen to your health problems and makes sure that you get the best of care this is the Pratice and doctor you will want to see. I have been with Dr Ronan ever since I got hurt at work 20 years ago and he has given me the best of care and I trust him with my life. He has found other doctors in helping me to be able to have the best care possible. He doesn’t give up and I don’t know where I would be without him.

When you struggle with finding a Dr who will actually listen, then you find an awesome dr like Dr. AJ Ronan, it is such a relief. Finally you are able to stop looking. You can talk to him, and know that he is paying attention and actually listening to what you are describing. Dr's like Dr. Ronan are few and far between and an absolute gem!

Dr. Arthur (AJ) Ronan has been a blessing in
managing my personal health care and health maintenance! My former PCP referred me to him, for OMT, back in 2011. When my former PCP told me I was maxed out on a med for cholesterol, I consulted with Dr. Ronan. He helped me manage my cholesterol and Diabetes more effectively than my former PCP. I’ve been with Dr. Ronan since 2012. He LISTENS and takes all the time I need (or he needs) to manage my health care!

He and his entire staff are WONDERFUL! His office is absolutely lovely, secure and clean. He has lab services, so I don’t need to go to another facility for bloodwork! I’m grateful that I can call or text Dr. Ronan 24/7, or when I’m at our vacation home in Florida. He responds within minutes!

Dr. AJ Ronan is more than my Primary Care Physician, he’s a great mentor and friend!! If there were a hundred stars he would receive that!! …Thank You, Dr. AJ Ronan!

Frequently Asked Questions

Doctors who operate in the MDVIP models typically see far fewer patients than traditional primary care doctors. That gives them more time to develop deeper doctor-patient relationships that can lead to better outcomes. They can also offer conveniences that most primary care doctors can’t, including same- and next-day appointments. They’re available after hours for urgent matters. And they have time to focus on prevention. That focus begins with the MDVIP Wellness Program, which patients pay for with their annual membership fee.

Most MDVIP-affiliated primary care practices accept insurance (your physician can tell you whether they accept your specific insurance plan). Your annual fee pays for preventive care medical services that insurance usually doesn’t cover (e.g., advanced diagnostic testing and screenings). Your MDVIP-affiliated physician will continue to bill your insurance and charge copays, co-insurances and deductibles as he or she currently does for other medical services like sick visits.

MDVIP makes wellness and prevention easier by providing your physician with innovative tools and technology. MDVIP supports your physician’s practice and seeks to eliminate barriers to a positive healthcare experience. Your doctor will determine whether and how to incorporate these tools at his/her discretion.
